I have a combox i bind it with data table like this.
cbclientid.DataSource = dsclientid;
cbclientid.DisplayMember = "Client_Info.Client_Name";
cbclientid.ValueMember = "Client_Info.Client_Id";
Now when i get value from table through sql reader.
Client Id how i select the value from cbclient(combox);
I am doing this :-
cbclientid.SelectedText = dr2.GetString(2); // Return Client Name
this code not select cbclient name value.

Try this:
cbclientid.SelectedIndex = cbclientid.FindString(dr2.getstring(2))

There is a treeview, I want to store all of the nodes into a class or structure.
How to do?

Have read about some macros but never found one wich works?
Anyone knows how to do this in VB.NET ... In C# it seems to be default.

Hi. I am developing a system that uses a computer that has a USB port as input with no keyboard/mouse. After the program scanned the flash drive, the user will now remove it. How can I duplicate the action of clicking the "Safely Remove Hardware" in my program?
Thanks a lot!

I tried this for days but can't seem to get it. Basically I just need to open a folder. No browsing or dialog box is needed. I just need to open a specific folder(E.g. "C:\Example\") whenever I click the button. I should be able to see whatever files are in there.
|
|
|
|
|
you want explorer to open the folder so you can see it?? you want cmd to display the folder? You want to open a display window in your program that displays the list of files in a folder? Please elaborate your problem.. Also show us some code that isn't working?

I can create a new instance for the MS Office app with the shell statement:
Shell("C:\Program Files\Microsoft Office\Office11\WINWORD.EXE ")
but I can not figure out the proper syntax to call a specific word document in a folder.
Shell("c:\Documents and Settings\Administrator\My Documents\Docs\Analysis.doc")
**I still get file not found in my catch block
*It does work with notepad
Shell("notepad C:\Documents and Settings\Administrator\My Documents\Analysis.doc")
Am I missing a project reference, a com object or a import statement? 
|

Have you tried:
Shell("C:\Program Files\Microsoft Office\Office11\WINWORD.EXE " & """" & "c:\Documents and Settings\Administrator\My Documents\Docs\Analysis.doc" & """")
|
|
|
|
|
I just knew it would take 2 or three sets of quotes...(yeah right)
What does the ampersand do?
|
|
|
|
|
Ampersand concatenates the strings into one string. The """" adds quotation marks, which are required because the file path has spaces.
VB reads the resulting command line as:
C:\Program Files\Microsoft Office\Office11\WINWORD.EXE "c:\Documents and Settings\Administrator\My Documents\Docs\Analysis.doc"
Not sure why you can have spaces in the executable path without adding quotes.
|
|
|
|
|
if you just like to open a .doc file you also can do this by
Process.Start("c:\Documents and Settings\Administrator\My Documents\Docs\Analysis.doc")
|
|
|
|
|
Thanks alot, Process.Start requires less keystrokes to process. I have found a invaluable resource here at the Code Project. Way Cool...

Hello everybody,
I've cretaed a database application that build tables/triggers/stored-procedures at runtime (Oracle DB 10g).
After all tables created, the application starts creating the triggers and the SPs.
this is small code:
--------------------------------------------------------------------------------
Public Shared Sub CreateTriggers()
Dim Err As String = ""
Dim HasErr As Boolean = False
Dim CmdTmp As OleDbCommand = New OleDbCommand
With CmdTmp
.Connection = oConn
'creating trigger(s)
.CommandText = "CREATE TRIGGER change_status AFTER INSERT ON invoices " & _
"REFERENCING NEW AS newRow FOR EACH ROW " & _
"BEGIN update orders set orders.order_status='Close' where orders.orderID = :newRow.orderID; " & _
"END change_status;"
.CommandType = CommandType.Text
Try
.ExecuteNonQuery()
Catch ex As Exception
HasErr = True
Err += ex.Message + Chr(13)
End Try
'creating stored-procedure(s)
.CommandText = "CREATE OR REPLACE PROCEDURE Add_Inventory(SID varchar2, IID varchar2, Amount Number ) " & _
"IS " & _
"BEGIN " & _
"Insert Into Inventory(StoreID, ItemID, Inv_Amount, Inv_DateM, Inv_DateY) " & _
"Values(SID, IID, Amount, To_Number(To_Char(SysDate, 'MM')), To_Number(To_Char(SysDate, 'YYYY'))); " & _
"END;"
Try
.ExecuteNonQuery()
Catch ex As Exception
HasErr = True
Err += ex.Message + Chr(13)
End Try
...
...
--------------------------------------------------------------------------------
now, I dont get exceptions when the app runs, but the triggers\SPs were NOT created..
I also created tables at run-time and there is no problem..the tables have been created...
There is no problem creating the triggers\SPs from sqlplus with the same user
so I dont think that is a permissions problem
(when I copy the trigger/SP code & paste it in sqlplus, I get the message(s)
Trigger created
or
procedure created )
I also CAN delete trigger(s)\SP(s) from the application but CANNOT create them..
what could be the problem?
please help me out here..I'm stuck...
Thank You
RoyRose

Hey,
Well, I guess this some kind of bug that OleDbCommand cannot create trigger or SPs but when I changed the objects to Oracle object (OracleConnection, OracleCommand, OracleDataAdapet, OracleTransaction..)
Everything works!
Thank You

What was your email address ?
Basically, make all your controls owner drawn, and get the paths to the images to draw on them from a config file.

Let say we have a class 'car' and it has an attribute 'color'. We can easly create 2 instance of car and set their color as:
Dim car1 as New Car
Dim car2 as New Car
car1.color = "red"
car2.color = "blue"
However if we need to create many instances of car then this method is limited. I want to write a procedure which can receives the name of instance and the color as parameters and then creates the instance and set the color.
Private Sub xyz(insName As string, colName as String)
dim insName as New Car
insName.color = colName
End Sub
|
|
|
|
|
Dim insName As New Car will not work.
Typically what you do in this scenario is create a collection of Car objects and then retrieve the instance you want by a key string value.
Dim colCars As New Collection
Private Sub CreateNewCar(ByVal colName As String, ByVal Key As String)
Dim oCar As New Car
oCar.Color = colName
colCars.Add(oCar, Key)
End Sub
Then retrieve an instance by
Dim oCar As Car
oCar = colCars(Key)
etc.
